而且，最好的方式是使用现有的标准。

因此，甚至在开发 **FastAPI** 前，我就花了几个月的时间研究 OpenAPI、JSON Schema、OAuth2 等规范。深入理解它们之间的关系、重叠及区别之处。

## 设计

然后，我又花了一些时间从用户角度（使用 FastAPI 的开发者）设计了开发者 **API**。

同时，我还在最流行的 Python 代码编辑器中测试了很多思路，包括 PyCharm、VS Code、基于 Jedi 的编辑器。

根据最新 <a href="https://www.jetbrains.com/research/python-developers-survey-2018/#development-tools" class="external-link" target="_blank">Python 开发者调研报告</a>显示，这几种编辑器覆盖了约 80% 的用户。

        }

        void mergeAll(Collection<V> vs, Remapping<V> remapping) {
            if (map == null) {
                map = new LinkedHashMap<>(list.size() + vs.size());
                for (V v : list) {
                    map.put(keyComputer.key(v), v);
                }
                list = null;
            }
            if (vs instanceof MergingList mergingList && mergingList.map != null) {

        checkArgument(
            fromUpperBounds.length == toUpperBounds.length
                && fromLowerBounds.length == toLowerBounds.length,
            "Incompatible type: %s vs. %s",
            fromWildcardType,
            to);
        for (int i = 0; i < fromUpperBounds.length; i++) {
          populateTypeMappings(mappings, fromUpperBounds[i], toUpperBounds[i]);
        }

Specific security vs. connectivity decisions are implemented by [ConnectionSpec](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-connection-spec/). OkHttp includes four built-in connection specs:

## 사용해봅시다!

이제 아래의 클래스를 이용해서 의존성을 정의할 수 있습니다.

{* ../../docs_src/dependencies/tutorial002.py hl[19] *}

**FastAPI**는 `CommonQueryParams` 클래스를 호출합니다. 이것은 해당 클래스의 "인스턴스"를 생성하고 그 인스턴스는 함수의 매개변수 `commons`로 전달됩니다.

## 타입 힌팅 vs `Depends`

위 코드에서 `CommonQueryParams`를 두 번 작성한 방식에 주목하십시오:

```Python
commons: CommonQueryParams = Depends(CommonQueryParams)
```

마지막 `CommonQueryParams` 변수를 보면:

```Python

        final StringSearchInterpolator interpolator = new StringSearchInterpolator();
        interpolator.setCacheAnswers(true);
        for (ValueSource vs : valueSources) {
            interpolator.addValueSource(vs);
        }
        for (InterpolationPostProcessor postProcessor : postProcessors) {
            interpolator.addPostProcessor(postProcessor);
        }

      "type": "type_error.integer"
    }
  ],
  "body": {
    "title": "towel",
    "size": "XL"
  }
}
```

#### `HTTPException` в FastAPI или в Starlette { #fastapis-httpexception-vs-starlettes-httpexception }

**FastAPI** имеет собственный `HTTPException`.

Класс ошибок **FastAPI** `HTTPException` наследует от класса ошибок Starlette `HTTPException`.
